CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation under 35 U.S.C. § 120 of U.S.application Ser. No. 15/204,361, filed Jul. 7, 2016, the entire contentsof each of which is incorporated herein by reference.

BACKGROUND Field

The present disclosure relates to electronic vaping and/or e-vapingdevices.

Description of Related Art

E-vaping devices, also referred to herein as electronic vaping devices(EVDs) may be used by adult vapers for portable vaping. Flavored vaporswithin an e-vaping device may be used to deliver a flavor along with thevapor that may be produced by the e-vaping device. The flavored vaporsmay be delivered via a flavor system.

In some cases, a loss of flavoring in a flavored vapor from a flavorsystem may occur when the flavor system is exposed to a heat source. Insome cases, a loss of flavoring in a flavored vapor may occur as aresult of chemical reactions between the flavor system elements orthermal degradation at a sufficiently high temperature.

Such a loss of flavoring from a flavoring system may reduce a sensoryexperience provided by an e-vaping device in which the flavoring systemis included.

Some detailed example embodiments are disclosed herein. However,specific structural and functional details disclosed herein are merelyrepresentative for purposes of describing example embodiments. Exampleembodiments may, however, be embodied in many alternate forms and shouldnot be construed as limited to only the example embodiments set forthherein.

Accordingly, while example embodiments are capable of variousmodifications and alternative forms, example embodiments thereof areshown by way of example in the drawings and will herein be described indetail. It should be understood, however, that there is no intent tolimit example embodiments to the particular forms disclosed, but to thecontrary, example embodiments are to cover all modifications,equivalents, and alternatives falling within the scope of exampleembodiments. Like numbers refer to like elements throughout thedescription of the figures.

It should be understood that when an element or layer is referred to asbeing “on,” “connected to,” “coupled to,” or “covering” another elementor layer, it may be directly on, connected to, coupled to, or coveringthe other element or layer or intervening elements or layers may bepresent. In contrast, when an element is referred to as being “directlyon,” “directly connected to,” or “directly coupled to” another elementor layer, there are no intervening elements or layers present. Likenumbers refer to like elements throughout the specification. As usedherein, the term “and/or” includes any and all combinations of one ormore of the associated listed items.

It should be understood that, although the terms first, second, third,etc. may be used herein to describe various elements, elements, regions,layers and/or sections, these elements, elements, regions, layers,and/or sections should not be limited by these terms. These terms areonly used to distinguish one element, element, region, layer, or sectionfrom another region, layer, or section. Thus, a first element, element,region, layer, or section discussed below could be termed a secondelement, element, region, layer, or section without departing from theteachings of example embodiments.

Spatially relative terms (e.g., “beneath,” “below,” “lower,” “above,”“upper,” and the like) may be used herein for ease of description todescribe one element or feature's relationship to another element(s) orfeature(s) as illustrated in the figures. It should be understood thatthe spatially relative terms are intended to encompass differentorientations of the device in use or operation in addition to theorientation depicted in the figures. For example, if the device in thefigures is turned over, elements described as “below” or “beneath” otherelements or features would then be oriented “above” the other elementsor features. Thus, the term “below” may encompass both an orientation ofabove and below. The device may be otherwise oriented (rotated 90degrees or at other orientations) and the spatially relative descriptorsused herein interpreted accordingly.

The terminology used herein is for the purpose of describing variousexample embodiments only and is not intended to be limiting of exampleembodiments. As used herein, the singular forms “a,” “an,” and “the” areintended to include the plural forms as well, unless the context clearlyindicates otherwise.

Thus, example embodiments should not be construed aslimited to the shapes of regions illustrated herein but are to includedeviations in shapes that result, for example, from manufacturing.

Unless otherwise defined, all terms (including technical and scientificterms) used herein have the same meaning as commonly understood by oneof ordinary skill in the art to which example embodiments belong. Itwill be further understood that terms, including those defined incommonly used dictionaries, should be interpreted as having a meaningthat is consistent with their meaning in the context of the relevant artand will not be interpreted in an idealized or overly formal senseunless expressly so defined herein.

FIG. 1A is a side view of an e-vaping device 60 according to someexample embodiments. FIG. 1B is a cross-sectional view along line IB-IB′of the e-vaping device of FIG. 1A. The e-vaping device 60 may includeone or more of the features set forth in U.S. Patent ApplicationPublication No. 2013/0192623 to Tucker et al. filed Jan. 31, 2013 andU.S. Patent Application Publication No. 2013/0192619 to Tucker et al.filed Jan. 14, 2013, the entire contents of each of which areincorporated herein by reference thereto. As used herein, the term“e-vaping device” is inclusive of all types of electronic vapingdevices, regardless of form, size or shape.

Referring to FIG. 1A and FIG. 1B, an e-vaping device 60 includes areplaceable cartridge (or first section) 70 and a reusable power supplysection (or second section) 72. The sections 70, 72 may be coupledtogether at complimentary interfaces 74, 84 of the respective sections70, 72.

In some example embodiments, the interfaces 74, 84 are threadedconnectors. It should be appreciated that an interface 74, 84 may be anytype of connector, including, without limitation, a snug-fit, detent,clamp, bayonet, and/or clasp.

As shown in FIG. 1A and FIG. 1B, in some example embodiments, an outletend insert 20 may be positioned at an outlet end of the cartridge 70.The outlet end insert 20 includes at least one outlet port 21 that maybe located off-axis from the longitudinal axis of the e-vaping device60. One or more of the outlet ports 21 may be angled outwardly inrelation to the longitudinal axis of the e-vaping device 60. Multipleoutlet ports 21 may be uniformly or substantially uniformly distributedabout the perimeter of the outlet end insert 20 so as to substantiallyuniformly distribute vapor drawn through the outlet end insert 20 duringvaping. Thus, as a vapor is drawn through the outlet end insert 20, thevapor may move in different directions.

The cartridge 70 includes a vaporizer assembly 22 and an additiveassembly 24. The vaporizer assembly 22 may form a generated vapor 95,and the additive assembly 24 may form a flavored vapor 97 based onreleasing one or more additives into the generated vapor 95 formed bythe vaporizer assembly 22.

In some example embodiments, the additive assembly 24 is configured torelease one or more additives into the generated vapor 95 based ondesorbing one or more additives from one or more adsorbent materialsincluded in the additive assembly 24.

In some example embodiments, the additive assembly 24 is configured torelease one or more additives into the generated vapor 95 based ondesorption of the one or more additives from the one or more adsorbentmaterials. The one or more additives may be desorbed from the one ormore additive materials based on one or more elements of the generatedvapor 95 adsorbing on the one or more adsorbent materials, therebydisplacing the one or more additives on the one or more adsorbentmaterials. In some example embodiments, the additive assembly 24 reactswith one or more elements of the generated vapor 95 to release the oneor more additives.

As described further below, the one or more elements of the generatedvapor 95 may include one or more elements of a pre-vapor formulationfrom which the generated vapor 95 is formed. The one or more elementsmay include at least one of water, solvents, active ingredients,ethanol, plant extracts, and natural or artificial flavors. A pre-vaporformulation may include at least one of glycerin and propylene glycol.

Still referring to FIG. 1A and FIG. 1B, the cartridge 70 includes anouter housing 16 extending in a longitudinal direction and an inner tube62 coaxially positioned within the outer housing 16. The power supplysection 72 includes an outer housing 17 extending in a longitudinaldirection. In some example embodiments, the outer housing 16 may be asingle tube housing both the cartridge 70 and the power supply section72 and the entire e-vaping device 60 may be disposable. The outerhousing 16 may have a generally cylindrical cross-section. In someexample embodiments, the outer housing 16 may have a generallytriangular cross-section along one or more of the cartridge 70 and thepower supply section 72. In some example embodiments, the outer housing16 may have a greater circumference or dimensions at a tip end than atan outlet end of the e-vaping device 60.

The vaporizer assembly 22 includes inner tube 62, gasket 14, gasket 18,a reservoir 32 configured to hold a pre-vapor formulation, a dispensinginterface 34 configured to draw pre-vapor formulation from the reservoir32, and a heating element 36 configured to vaporize the drawn pre-vaporformulation.

At one end of the inner tube 62, a nose portion of gasket (or seal) 14is fitted into an end portion of the inner tube 62. An outer perimeterof the gasket 14 may provide a substantially airtight seal with aninterior surface of the outer housing 16. The gasket 14 includes apassage 15 that opens into an interior of the inner tube 62 that definesa channel 66. A space 38 at a backside portion of the gasket 14 assurescommunication between the passage 15 and one or more air inlet ports 44located between the gasket 14 and a connector element 91. The connectorelement 91 may be included in the interface 74.

In some example embodiments, a nose portion of gasket 18 is fitted intoanother end portion of the inner tube 62. An outer perimeter of thegasket 18 may provide a substantially airtight seal with an interiorsurface of the outer housing 16. The gasket 18 includes a passage 19disposed between the channel 66 of the inner tube 62 and the interior ofan outlet end insert 20. The passage 19 may transport a vapor from thechannel 66 to the outlet end insert 20 via the additive assembly 24.

In some example embodiments, at least one air inlet port 44 may beformed in the outer housing 16, adjacent to the interface 74 to minimizethe probability of an adult vaper's fingers occluding one of the portsand to control the resistance-to-draw (RTD) during vaping. In someexample embodiments, the air inlet ports 44 may be machined into theouter housing 16 with precision tooling such that their diameters areclosely controlled and replicated from one e-vaping device 60 to thenext during manufacture.

In some example embodiments, the air inlet ports 44 may be drilled withcarbide drill bits or other high-precision tools and/or techniques. Insome example embodiments, the outer housing 16 may be formed of metal ormetal alloys such that the size and shape of the air inlet ports 44 maynot be altered during manufacturing operations, packaging, and vaping.Thus, the air inlet ports 44 may provide consistent RTD. In some exampleembodiments, the air inlet ports 44 may be sized and configured suchthat the e-vaping device 60 has a RTD in the range of from about 60 mmH₂O to about 150 mm H₂O.

Still referring to FIG. 1A and FIG. 1B, the reservoir 32 may include apre-vapor formulation. The space defined between the gaskets 14 and 18,the outer housing 16 and the inner tube 62 may establish the confines ofthe reservoir 32, such that the reservoir 32 may be contained in anouter annulus between the inner tube 62, the outer housing 16 and thegaskets 14 and 18. Thus, the reservoir 32 may at least partiallysurround the channel 66.

The dispensing interface 34 is coupled to the reservoir 32, such thatthe dispensing interface 34 may extend transversely across the channel66 between opposing portions of the reservoir 32. The dispensinginterface 34 is configured to draw pre-vapor formulation from thereservoir 32.

The heating element 36 is coupled to the dispensing interface 34 and isconfigured to generate heat. As shown in the example embodimentillustrated in FIG. 1B, the heating element 36 may extend transverselyacross the channel 66 between opposing portions of the reservoir 32. Insome example embodiments, the heating element 36 may extend parallel toa longitudinal axis of the channel 66.

The dispensing interface 34 is configured to draw pre-vapor formulationfrom the reservoir 32, such that the pre-vapor formulation may bevaporized from the dispensing interface 34 based on heating of thedispensing interface 34 by the heating element 36.

During vaping, pre-vapor formulation may be transferred from thereservoir 32 and/or storage medium in the proximity of the heatingelement 36 via capillary action of a dispensing interface 34. Thedispensing interface 34 may include a first end portion and a second endportion. The first and second end portions of the dispensing interface34 may extend into opposite sides of the reservoir 32. Dispensinginterface 34 end portions may be referred to herein as roots. Theheating element 36 may at least partially surround a central portion ofthe dispensing interface 34 such that if and/or when the heating element36 is activated to generate heat, the pre-vapor formulation in thecentral portion of the dispensing interface 34 may be vaporized by theheating element 36 to form a vapor. The central portion of a dispensinginterface 34 may be referred to herein as a trunk.

The reservoir 32 may include a pre-vapor formulation which is free offlavorants, such that if and/or when the vaporizer assembly 22 forms avapor 95, via vaporization of a pre-vapor formulation by the heatingelement 36, the vapor 95 may be substantially absent of flavor, therebybeing a “generated vapor.” Such an absence of flavorants in thereservoir 32 of the vaporizer assembly 22 may result in mitigation ofchemical reactions between pre-vapor formulation materials and theflavorants in the reservoir 32 and upon vaporization as a result ofheating of the pre-vapor formulation by the heating element 36.

Still referring to FIG. 1A and FIG. 1B, the additive assembly 24 ispositioned between the vaporizer assembly 22 and the outlet end insert20. As shown in FIG. 1B, the additive assembly 24 may be spaced apartfrom the vaporizer assembly 22 such that at least the additive assembly24, vaporizer assembly 22, and outer housing 16 define a space 40between the additive assembly 24 and the vaporizer assembly 22. Agenerated vapor 95 formed by the vaporizer assembly 22 may pass throughspace 40 such that the generated vapor 95 is in fluid communication withthe additive assembly 24. In some example embodiments, the additiveassembly 24 is located within the space 40 such that a generated vapor95 may pass around at least one outer surface of the additive assembly24 through the space 40.

The additive assembly 24 is configured to form a flavored vapor 97 basedon releasing one or more additives into a generated vapor 95 passing influid communication with one or more portions of the additive assembly24.

The additive assembly 24 is positioned in fluid communication with boththe vaporizer assembly 22 and the outlet end insert 20. The cartridge 70may be configured to direct generated vapor 95 formed by the vaporizerassembly 22 to exit the cartridge 70 via the outlet ports 21. Thecartridge 70 may further be configured to direct the generated vapor 95to pass in fluid communication with the additive assembly 24 towards theoutlet ports 21. Passing in fluid communication with the additiveassembly 24 may include passing through at least a portion of theadditive assembly 24.

The additive assembly 24 may hold an additive and may be configured torelease the additive into a generated vapor 95 formed by the vaporizerassembly 22 to form a flavored vapor 97. As described further below, insome example embodiments the additive is carbon dioxide, and theadditive assembly 24 may include one or more adsorbent materials ontowhich carbon dioxide is adsorbed. The additive assembly 24 may beconfigured to release an additive that is carbon dioxide into thegenerated vapor 95 to form a flavored vapor 97. The additive assembly 24may release the carbon dioxide into the generated vapor 95 based on oneor more elements of the generated vapor 95 adsorbing onto the adsorbentmaterial.

The additive assembly 24, as discussed further below, may include aporous structure. The porous structure may hold an additive in fluidcommunication with at least one of the vaporizer assembly 22 and thespace 40, so that generated vapor 95 may pass at least partially throughthe porous structure and in fluid communication with the additive heldin the porous structure. The generated vapor 95 may act as an eluent,eluting the additive from the porous structure and into the generatedvapor 95 to form an eluate. The eluate may include the generated vapor95 and the additive. Such an eluate may be referred to as the flavoredvapor 97.

In some example embodiments, an additive eluted into the generated vapor95 is in a particulate phase. A particulate phase may include a liquidphase, solid phase, or the like. In some example embodiments, anadditive eluted into the generated vapor 95 is in a vapor phase, gasphase, etc. An additive may include a volatile flavor substance, and thevolatile flavor substance may be eluted into the generated vapor 95. Insome example embodiments, an additive eluted into the generated vapor 95includes a nonvolatile flavor substance.

In some example embodiments, if and/or when the additive assembly 24holds the additive separate from the vaporizer assembly 22 and thecartridge 70 is configured to direct generated vapor 95 through theadditive assembly 24 subsequent to formation of the generated vapor 95,the generated vapor 95 may be cooled from an initial temperature atformation in the vaporizer assembly 22. Where the generated vapor 95passing through the additive assembly 24 is cooled from the initialtemperature, chemical reactions between the additive eluted into thegenerated vapor 95 and the elements of the generated vapor 95 may be atleast partially mitigated.

In some example embodiments, if and/or when the e-vaping device 60includes an additive assembly 24 that holds an additive separate fromthe vaporizer assembly 22, the e-vaping device 60 may be configured tomitigate a probability of chemical reactions between the additive andone or more elements of the vaporizer assembly 22. An absence of suchchemical reactions may result in an absence of reaction products in theflavored vapor 97. Such reaction products may detract from a sensoryexperience provided by the flavored vapor 97. As a result, an e-vapingdevice 60 that is configured to mitigate the probability of suchchemical reactions may provide a more consistent and improved sensoryexperience through the flavored vapor 97.

In some example embodiments, the additive included in an e-vaping device60 may be replaceable independently of the pre-vapor formulation in thecartridge 70, as the flavorants are included in an additive assembly 24that is separate from the vaporizer assembly 22 in which the pre-vaporformulation is included. The additive assembly 24 may be replaced withanother additive assembly 24 to swap the additive included in thee-vaping device 60 as desired by an adult vaper. The additive assembly24 may be replaced with another additive assembly 24 to replenishadditives in the e-vaping device 60 without replacing a vaporizerassembly 22, where the vaporizer assembly 22 may include sufficientpre-vapor formulation to support additional vaping.

In some example embodiments, one or more of the interfaces 74, 84include one or more of a cathode connector element and an anodeconnector element. In the example embodiment illustrated in FIG. 1B, forexample, electrical lead 68-2 is coupled to the interface 74. As furthershown in FIG. 1B, the power supply section 72 includes a lead 92 thatcouples the control circuitry 11 to the interface 84. If and/or wheninterfaces 74, 84 are coupled together, the coupled interfaces 74, 84may electrically couple leads 68-2 and 92 together.

In some example embodiments, the cartridge 70 includes a connectorelement 91. Connector element 91 may include one or more of a cathodeconnector element and an anode connector element. In the exampleembodiment illustrated in FIG. 1B, for example, electrical lead 68-1 iscoupled to the connector element 91. As further shown in FIG. 1B, theconnector element 91 is configured to couple with a power supply 12included in the power supply section 72. If and/or when interfaces 74,84 are coupled together, the connector element 91 and power supply 12may be coupled together. Coupling connector element 91 and power supply12 together may electrically couple lead 68-1 and power supply 12together.

The connector element 91 may include an insulating material 91 b and aconductive material 91 a. The conductive material 91 a may electricallycouple lead 68-1 to power supply 12, and the insulating material 91 bmay insulate the conductive material 91 a from the interface 74, suchthat a probability of an electrical short between the lead 68-1 and theinterface 74 is reduced and/or prevented. For example, if and/or whenthe connector element 91 includes a cylindrical cross-section orthogonalto a longitudinal axis of the e-vaping device 60, the insulatingmaterial 91 b included in connector element 91 may be in an outerannular portion of the connector element 91 and the conductive material91 a may be in an inner cylindrical portion of the connector element 91,such that the insulating material 91 b surrounds the conductive material91 a and reduces and/or prevents a probability of an electricalconnection between the conductive material 91 a and the interface 74.

Still referring to FIG. 1A and FIG. 1B, the power supply section 72includes a sensor 13 responsive to air drawn into the power supplysection 72 via an air inlet port 44 a adjacent to a free end or tip endof the e-vaping device 60, at least one power supply 12, and controlcircuitry 11. The power supply 12 may include a rechargeable battery.The sensor 13 may be one or more of a pressure sensor, amicroelectromechanical system (MEMS) sensor, etc.

In some example embodiments, the power supply 12 includes a batteryarranged in the e-vaping device 60 such that the anode is downstream ofthe cathode. A connector element 91 contacts the downstream end of thebattery. The heating element 36 is connected to the power supply 12 byat least lead 68-1 and connector element 91 if and/or when interfaces74, 84 are coupled together.

The power supply 12 may be a Lithium-ion battery or one of its variants,for example a Lithium-ion polymer battery. Alternatively, the powersupply 12 may be a nickel-metal hydride battery, a nickel cadmiumbattery, a lithium-manganese battery, a lithium-cobalt battery or a fuelcell. The e-vaping device 60 may be usable by an adult vaper until theenergy in the power supply 12 is depleted or in the case of lithiumpolymer battery, a minimum voltage cut-off level is achieved.

Further, the power supply 12 may be rechargeable and may includecircuitry configured to allow the battery to be chargeable by anexternal charging device. To recharge the e-vaping device 60, aUniversal Serial Bus (USB) charger or other suitable charger assemblymay be used.

Upon completing the connection between the cartridge 70 and the powersupply section 72, the at least one power supply 12 may be electricallyconnected with the heating element 36 of the cartridge 70 upon actuationof the sensor 13. Air is drawn primarily into the cartridge 70 throughone or more air inlet ports 44. The one or more air inlet ports 44 maybe located along the outer housing 16, 17 of the first and secondsections 70, 72 or at one or more of the coupled interfaces 74, 84.

The sensor 13 may be configured to sense an air pressure drop andinitiate application of voltage from the power supply 12 to the heatingelement 36. As shown in the example embodiment illustrated in FIG. 1B,some example embodiments of the power supply section 72 include a heateractivation light 48 configured to glow if and/or when the heatingelement 36 is activated.

FIG. 2A is a plan view of an additive assembly 24 according to someexample embodiments. FIG. 2B is a plan view of an additive assembly 24according to some example embodiments. FIG. 2C is a plan view of anadditive assembly 24 according to some example embodiments. FIG. 2D is aplan view of an additive assembly 24 according to some exampleembodiments. Each of the example embodiments of the additive assembly 24shown in FIG. 2A, FIG. 2B, FIG. 2C, and FIG. 2D may be included in anyof the embodiments included herein, including the additive assembly 24shown in FIG. 1B.

In some example embodiments, the additive assembly 24 includes one ormore adsorbent materials on which carbon dioxide is adsorbed. Theadditive assembly 24 may be configured to release the carbon dioxideinto a generated vapor 95 to form a flavored vapor 97, based on one ormore elements of the generated vapor 95 adsorbing onto the adsorbentmaterials. The adsorbent materials may include one or more of amonolithic material, and a plurality of adsorbent material structures.An adsorbent material structure may include a bead structure, such thata plurality of adsorbent material structures may include a plurality ofadsorbent beads.

In the example embodiments illustrated in FIG. 2A and FIG. 2B, forexample, the additive assemblies 24 each include a plurality ofadsorbent material beads 202 on which carbon dioxide 210 is adsorbed. Anadditive assembly 24 may include one or more various adsorbent materialsconfigured to adsorb carbon dioxide. For example, one or more of theadsorbent material beads 202 may include at least one of zeolite,silica, activated carbon, and molecular sieves.

As shown in FIG. 2A and FIG. 2B, the additive assembly 24 may beconfigured to direct generated vapor 95 through the plurality of beads202 to elute at least some of the carbon dioxide 210 into the generatedvapor 95 to form the flavored vapor 97. The carbon dioxide 210 may beeluted into the generated vapor 95 based on desorption of the carbondioxide 210 from one or more of the adsorbent material beads 202. Thecarbon dioxide 210 may be desorbed from an adsorbent material bead 202based on one or more elements of the generated vapor 95 adsorbing on theadsorbent material of a bead 202 such that the carbon dioxide 210 isdisplaced from the adsorbent material.

In the example embodiments illustrated in FIGS. 2A-B, the carbon dioxide210 is illustrated as being adsorbed on to the surfaces on an exteriorof the adsorbent material beads 202. It will be understood that, in someexample embodiments, the carbon dioxide 210 may be at least partiallydistributed throughout an interior of one or more adsorbent materials,including one or more adsorbent material beads 202. The carbon dioxide210 may be adsorbed to internal surfaces, including one or more internalpore surfaces, in an interior of the adsorbent material and distributedinto the interior of the adsorbent material. In some exampleembodiments, carbon dioxide 210 is both adsorbed on to one or moreexternal surfaces of an adsorbent material, including one or moreexternal pore surfaces, and adsorbed on to one or more internalsurfaces, including one or more internal pore surfaces. The carbondioxide 210 may thus be distributed throughout at least a portion of aninterior of the adsorbent material in addition to being on an externalsurface of the adsorbent material.

In some example embodiments, the additive assembly 24 at least partiallyencloses the one or more adsorbent material structures in a containmentstructure. The containment structure may be configured to hold the oneor more adsorbent material structures in a fixed volume. The containmentstructure may include one or more openings and may be configured todirect a generated vapor 95 through an interior of the containmentstructure to pass in fluid communication with one or more adsorbentmaterial structures.

In the example embodiments illustrated in FIG. 2A and FIG. 2B, forexample, the additive assembly 24 includes a containment structure 201that at least partially encloses the adsorbent material beads 202. Thecontainment structure 201 includes openings 212, 214 and is configuredto direct the generated vapor 95 through opening 212 to elute carbondioxide 210 into the generated vapor 95. The containment structure 201may direct flavored vapor 97 out of the additive assembly 24 throughopening 214. In some example embodiments, the containment structure 201at least partially includes a mesh structure. For example, thecontainment structure 201 may include a mesh structure that covers atleast one of openings 212, 214. The mesh structure may be partiallypermeable, such that the mesh structure is configured to direct vapor95, 97 across the mesh and restrict at least the adsorbent materialbeads 202 from passing through one or more of the openings 212, 214.

In some example embodiments, the additive assembly 24 includes one ormore flavor materials that hold one or more flavorants. The one or moreflavor materials may release the one or more flavorants into thegenerated vapor 95 if and/or when the generated vapor 95 passes in fluidcommunication with the flavor materials.

An additive assembly 24 that includes an adsorbent material and a flavormaterial may be configured to release both carbon dioxide and one ormore flavorants into the generated vapor 95 to form a flavored vapor 97.In the example embodiments illustrated in FIG. 2A and FIG. 2B, forexample, the additive assemblies 24 include flavor materials 204, 206 inaddition to the adsorbent material beads 202.

As shown in FIG. 2A and FIG. 2B, a flavor material may have one or morevarious shapes. For example, in the example embodiment illustrated inFIG. 2A, the flavor material 204 is a “shredded” material having afibrous shape. The flavor material 204 extends between adsorbentmaterial beads 202 throughout the interior of the additive assembly 24.In another example, in the example embodiment illustrated in FIG. 2B,the flavor material 206 is a bead-shaped material that is packed withthe adsorbent material beads 202 into the additive assembly 24. In someexample embodiments, one or more of the flavor materials 204, 206included in an additive assembly includes at least one botanicalsubstance, and the at least one botanical substance includes theflavorant.

In the illustrated example embodiments of FIG. 2A and FIG. 2B, theadditive assemblies 24 each include a uniform or substantially uniformmixture of adsorbent material beads 202 and at least one of the flavormaterials 204, 206. For example, in the illustrated example embodimentof FIG. 2B, the adsorbent material beads 202 and flavor material beads206 are substantially uniformly mixed.

In some example embodiments, the mixture of adsorbent materials andflavor materials in the additive assembly 24 may be a non-uniformmixture. For example, a concentration of flavor materials in theadditive assembly 24 may be greater with increased proximity to theopening 214, relative to the opening 212. As a result, a generated vapor95 passing in fluid communication with the flavor materials may includecarbon dioxide released from adsorbent material beads 202 that arecloser to the opening 212 than the opening 214.

In some example embodiments, an adsorbent material included in theadditive assembly 24 may be configured to generate heat based on one ormore elements of generated vapor 95 adsorbing on the adsorbent material,such that the adsorbent material is configured to release both carbondioxide and heat if and/or when one or more elements of the generatedvapor 95 adsorb onto the adsorbent material. For example, an adsorbentmaterial bead 202 may release heat based on one or more elements of thegenerated vapor 95 adsorbing onto the adsorbent material bead 202 anddisplacing at least some carbon dioxide 210 from the adsorbent materialbead 202.

In some example embodiments, one or more flavor materials included inthe additive assembly 24 are configured to absorb the heat generated bythe adsorbent material included in the additive assembly 24. A flavormaterial may release an increased amount of flavorant, via elution intoa generated vapor 95, based on an increased temperature of the flavormaterial. If and/or when the flavor material absorbs heat generated byadsorbent material in the additive assembly 24, the flavor material mayrelease an increased amount of flavorant into the generated vapor 95,relative to an unheated flavor material.

In the example embodiments illustrated in FIG. 2A and FIG. 2B, theadditive assembly 24 is configured to enable improved elution offlavorant into a generated vapor 95 based on elution of carbon dioxide210 into the generated vapor 95. The additive material beads 202included in the additive assemblies 24 shown in FIG. 2A and FIG. 2B areconfigured to generate heat based on adsorption of compounds from withinthe vapor 95. The generated heat may be absorbed by flavor materials204, 206 to heat the flavor materials 204, 206. Flavorants may be elutedfrom the flavor materials 204, 206 into a generated vapor 95 passing influid communication with the additive assembly 24. The flavorant elutioninto the generated vapor 95 may be improved, relative to an additiveassembly 24 in which the adsorbent material beads 202 are absent, basedon the adsorbent material-generated heat that is absorbed by the flavormaterials 204, 206.

Referring to FIG. 2C and FIG. 2D, in some example embodiments, anadditive assembly 24 may include one or more structures that include atleast one of adsorbent material and flavor material. Such one or morestructures may be porous structures that include at least one ofadsorbed carbon dioxide and one or more flavorants. The one or morestructures may be configured to release at least one of carbon dioxideand one or more flavorants into a generated vapor 95 if and/or when thegenerated vapor 95 flows in fluid communication with the one or morestructures.

Referring to the example embodiment illustrated in FIG. 2C, the additiveassembly 24 includes a structure 220 configured to release at leastcarbon dioxide into a generated vapor 95 flowing in fluid communicationwith the structure 220. The structure 220 may be a porous structureconfigured to direct generated vapor 95 to flow through an interior ofthe structure 220. Carbon dioxide may be adsorbed on at least a portionof the internal structure of the structure 220. Carbon dioxide may bedesorbed from the internal structure of the structure 220 based on oneor more elements of the generated vapor 95 adsorbing on the internalstructure of the structure 220.

In some example embodiments, the structure 220 may hold one or moreflavorants within an internal structure of the structure 220. Thestructure 220 may be configured to enable elution of one or moreflavorants into a generated vapor 95 flowing through the internalstructure of structure 220.

In some example embodiments, the additive assembly 24 may includemultiple structures 220. Separate structures 220 may include differentones of an adsorbent material holding adsorbed carbon dioxide and aflavor material holding one or more flavorants. For example, an additiveassembly 24 may include a first structure 220 that is proximate to thevaporizer assembly 22 and a second structure 220 that is distal from thevaporizer assembly 22. The first structure 220 may include an adsorbentmaterial on which carbon dioxide is adsorbed, and the second structure220 may include a flavor material holding one or more flavorants. Agenerated vapor 95 formed by the vaporizer assembly 95 may first flow influid communication with the first structure 220 to elute carbon dioxidefrom the first structure 220 and carry heat generated by adsorbentmaterial included in the first structure 220. The generated vapor 95 maythen flow in fluid communication with the second structure 220 andtransfer the carried heat to the second structure 220. The generatedvapor 95 may elute one or more flavorants from the second structure 220,where flavorant elution is based at least in part upon the heattransferred to the second structure 220.

In some example embodiments, the structure 220 may be configured torelease one or more of carbon dioxide and one or more flavorants into agenerated vapor 95 flowing in fluid communication with an outer surfaceof the structure 220. For example, the structure 220 may be configuredto direct the generated vapor 95 to flow around one or more outersurfaces of the structure 220. The structure 220 may include at leastone of carbon dioxide adsorbed to an outer surface and one or moreflavorants that may be eluted through an outer surface.

In some example embodiments, the additive assembly 24 may include astructure 220 that includes one or more internal passages through whicha generated vapor 95 may flow. At least one of carbon dioxide and one ormore flavorants may be released into a generated vapor 95 through theone or more internal passages. In the example embodiment illustrated inFIG. 2D, for example, the structure 220 defines an internal passage 240having openings 242, 244. The structure 220 shown in FIG. 2D may beconfigured to direct generated vapor 95 to enter the passage 240 throughopening 242 and exit the passage 240 through opening 244.

In some example embodiments, a portion of the structure 220 that definesan interior surface 241 of the passage 240 may include an adsorbentmaterial on which carbon dioxide may be adsorbed. The structure 220 maybe configured to desorb the carbon dioxide into a generated vapor 95passing through the passage 240 to form the flavored vapor 97, based onone or more elements of the generated vapor 95 adsorbing onto the one ormore portions of the structure 220 that define the interior surface 241of the passage 240.

As shown in FIG. 3, the adsorbent material 303 may, in addition toreleasing carbon dioxide 306 through desorption 308, generate heat 310based on one or more elements 302 of the generated vapor 95 adsorbingonto the adsorbent material beads 202. The heat 310 may be absorbed byone or more of the flavor material beads 206 included in the flavormaterial 305. The heat may be transferred to the flavor material 305through one or more of conduction, convection, and radiation. Forexample, if and/or when the flavor material beads 206 and adsorbentmaterial beads 202 are in physical contact, the generated heat 310 maybe transferred from the adsorbent material beads 202 to the flavormaterial beads 206 through conduction. In another example, the heat 310may be transferred to at least some of the flavor material beads 206 bythe modified vapor 96 through convection. In some example embodiments,heat generated in the system may facilitate (enable) the release of agreater amount of flavorant to modified vapor 96. Some flavorant maystransfer to stream 96 through an elution/entrainment type of mechanism(e.g., a concentration driven mechanism and/or concentration gradientbetween the flavorant carrier and the passing vapor). Such a transfermay occur even in the absence of heat generation at the adsorbentmaterial beads 202 and absorption at flavor material 305.

The flavor material 305 included in the additive assembly 24 may beconfigured to release one or more flavorants into a vapor flowing influid communication with the flavor material 305 based at least in partupon absorbing the heat 310 generated by the adsorbent material beads202. Based on the flavor material 305 and the adsorbent material beads202, the additive assembly 24 may be configured to form a flavored vapor97 that includes both carbon dioxide and one or more flavorants.

As shown in FIG. 3, the flavor material beads 206 may release the one ormore flavorants 312 based at least in part upon absorbing at least someof the heat 310 generated by the adsorbent material beads 202. At leastone of the rate of flavorant 312 released by the flavor material 305 andthe amount of flavorant 312 released by the flavor material 305 may varyin direct proportion to the amount of heat 310 absorbed by the flavormaterial 305. As a result, the flavor material 305 may be configured torelease more flavorant 312 into a vapor 95, 96 passing in fluidcommunication with the flavor material 305 if and/or when the flavormaterial 305 absorbs heat 310 from the adsorbent material beads 202,relative to the amount of flavorant 312 released by the flavor material305 into a vapor 95, 96 in the absence of absorbing such heat 310. Thus,flavorant 312 elution from the flavor material 305 may be augmented bythe flavor material 305 absorbing the heat 310 generated by theadsorbent material beads 202.

As shown in FIG. 3, if and/or when the flavorants 312 are released fromthe flavor material 206 into a modified vapor 96, the flavorants 312 maymix with the modified vapor 96 to form a flavored vapor 97. The flavoredvapor 97 may include one or more generated vapor elements 302, carbondioxide 310 released by the adsorbent material 303, and flavorants 312released by the flavor material 305. The flavored vapor 97 may exit theadditive assembly 24.

FIG. 6A is a cross-sectional view of an additive assembly 24 thatincludes multiple additive structures according to some exampleembodiments. The additive assembly 24 shown in FIG. 6A may be includedin any of the embodiments included herein, including the additiveassembly 24 shown in FIG. 1B.

In some example embodiments, an additive assembly 24 includes multipleadditive structures 604-1 to 604-N. The additive assembly 24 may includea configuration of multiple additive structures 604-1 to 604-N thatcollectively define one or more passages through the additive assembly24. The additive assembly 24 may be configured to direct a generatedvapor 95 through one or more of the passages 602-1 to 602-N to flow influid communication with one or more surfaces of the additive structures604-1 to 604-N.

As shown in FIG. 6A, additive assembly 24 includes additive structures604-1 to 604-N. The additive structures 604-1 to 604-N may each includeat least one of an adsorbent material and a flavor material. Differentadditive structures may include different materials. For example,additive structure 604-1 may include an adsorbent material on whichcarbon dioxide is adsorbed and additive structure 604-N may include aflavor material holding at least one flavorant.

In some example embodiments, one or more of the additive structures604-1 to 604-N is a monolithic structure that restricts generated vapor95 to flow along an outer surface of the respective one or more additivestructures 604-1 to 604-N.

As further shown in FIG. 6A, the additive structures 604-1 to 604-N maybe positioned in the additive assembly 24 in a configuration such thatthe additive structures 604-1 to 604-N at least partially define one ormore passages 602-1 to 602-N through the additive assembly 24. Theadditive assembly 24 shown in FIG. 6A may direct a generated vapor 95entering the additive assembly 24 to flow through at least one of thepassages 602-1 to 602-N such that the generated vapor 95 flows in fluidcommunication with an outer surface of at least one of the additivestructures 604-1 to 604-N.

Based on directing at least a portion of the generated vapor 95 to flowthrough one or more passages in fluid communication with an outersurface of one or more additive structures 604-1 to 604-N, the additiveassembly 24 may enable improved release of at least one of flavorant andcarbon dioxide into the generated vapor 95. For example, based onincluding multiple additive structures 604-1 to 604-N configured todefine multiple passages 602-1 to 602-N through the additive assembly24, the additive assembly 24 may include a greater additive structureouter surface area, relative to an additive assembly 24 that includes anindividual additive structure 604-1. Based on including such anincreased outer surface area, the additive assembly 24 shown in FIG. 6Amay be configured to provide improved release of one or more additivesinto a generated vapor 95 flowing in fluid communication with the one ormore additive structures 604-1 to 604-N.

FIG. 6B is a cross-sectional view of an additive assembly 24 thatincludes multiple additive structures 652-1 to 652-2 and 654 accordingto some example embodiments. The additive assembly 24 shown in FIG. 6Bmay be included in any of the embodiments included herein, including theadditive assembly 24 shown in FIG. 1B.

In some example embodiments, an additive assembly 24 may include aconfiguration of multiple additive structures that collectively defineone or more passages through the additive assembly 24. The one or morepassages may include portions having different orientations. A vaporflowing through the one or more passages may change direction based onflowing through differently-oriented passage portions. If and/or when avapor flows from a first passage portion having a first orientation toanother passage portion having a different orientation, the vapor mayimpinge on an outer surface of an additive structure. Additive releasefrom the additive structure may be improved, based on the impingement.

As shown in FIG. 6B, additive assembly 24 includes a configuration ofadditive structures 652-1 to 652-2 and 654 that collectively define apassage 606 through the additive assembly 24. The passage 606 includesportions having portions 608-1 and 608-2.

Additive structures 652-1 to 652-2 define a first portion 608-1 of thepassage 606 through the additive assembly 24. The first portion 608-1 ofthe passage 606 is oriented to extend in parallel or substantially inparallel with a longitudinal axis of the additive assembly 24.

Additive structures 652-1 to 652-2 and 654 at least partially defineportions 608-2 of the passage 606. Portions 608-2 are oriented to extendorthogonally or substantially orthogonally to the longitudinal axis ofthe additive assembly 24. As shown, the passage 606 first portion 608-1extends orthogonally or substantially orthogonally to an outer surface656 of the additive structure 654.

Based on the orientations of portions 608-1 and 608-2 of the passage606, a generated vapor 95 flowing through the passage 606 from portion608-1 to one of the portions 608-2 may impinge upon the outer surface656 of the additive structure 654.

In some example embodiments, the additive structure 654 may divert atleast a portion of the impinging generated vapor 95 to flow throughportions 608-2 of the passage 606 such that the generated vapor 95 flowsin fluid communication with one or more outer surfaces 656 of theadditive structure 654. Based on the generated vapor 95 impinging uponthe additive structure 654 outer surface 656, additive release from theadditive structure 654 into the generated vapor to form a flavored vapor97 a may be improved.

In some example embodiments, the additive structure 654 is a porousstructure, such that at least a portion of the generated vapor 95impinging on surface 656 may flow through the additive structure 654 toform a flavored vapor 97 b.
